TPD6S300ARUKR

TPD6S300ARUKR is Texas Instruments’ USB Type-C port protector in 20-pin WQFN — for shielding the CC and SBU lines from the most common Type-C failure: a short between the high-voltage VBUS pin and the adjacent low-voltage CC/SBU pins caused by debris or a damaged connector. It provides overvoltage protection on CC1/CC2 and SBU1/SBU2 plus IEC ESD protection, so a single contaminated connector cannot destroy the PD controller or the application processor behind it. -40 to +85°C, Active production status per TI’s datasheet addendum. Selection advice: this is a pure protection device, not a PD controller — pair it with a controller such as the TPS25751 or STUSB4500 on this site; for designs that also need the USB data-path mux, look at TI’s combo protection-plus-mux parts instead. Place it directly at the Type-C receptacle for the shortest possible fault path. Parameters verified against Texas Instruments documentation.
